As part of the immensely popular "Real Heroes" series, the 4th issue pays tribute to lifeguards worldwide, particularly those serving in the United States Coast Guard. As one of the six military services, its members have fulfilled their unique duty as a humanitarian and security force protecting America in both domestic and international waters for over 100 years. Although involved in every aspect of U.S. law enforcement and commerce on the high seas, the U.S. Coast Guard is a unique security force best known for its daring search and rescue operations, including medical evacuations, downed aviators, distressed vessels, floods, and hurricanes. Even today, these true heroes save countless lives in need, true to their motto "So others may live."
